Explicación paso a paso:

La configuración formará un triángulo de ángulos rectos.

Deje que el pie de la escalera a la pared sean los lados adyacentes = 2,5 m

La altura de la pared será el lado opuesto = 3,5 m

La longitud de la escalera será la hipotenusa.

Usando el teorema de Pitágoras:

hip² = opp² + adj²

hip² = 3,5² + 2,5²

hip² = 12,25 + 6,25

hip² = 6

hip = √6

hip = 2,45 m

Por tanto, la longitud de la escalera es 2,45 m.

Answer:An important category of percentage exercises is markup and markdown problems. For these, you calculate the markup or markdown in absolute terms (you find by how much the quantity changed), and then you calculate the percent change relative to the original value. So they're really just another form of "increase - decrease" exercises.

Answer:

Step-by-step explanation:

In the equation ...

  y = x² +3

the largest variable exponent is 2, which is not 1. The equation is not linear.

__

In the equation ...

  y = (1/4)x +7

the largest variable exponent is 1, so the equation is linear.

Answer:

x = 9

[tex] m\angle 1= 59\degree [/tex]

Step-by-step explanation:

Since, [tex] \angle 1 \:and \:\angle 3[/tex] are vertical angles.

[tex]\therefore m\angle 1 = m\angle 3\\

\therefore (5x + 14) \degree= (7x - 4) \degree\\

\therefore (5x + 14) = (7x - 4) \\

\therefore 5x - 7x = - 4 - 14\\

\therefore -2 x = - 18\\\\

\therefore x =\frac{-18}{-2}\\\\

\huge \orange {\boxed {\therefore x = 9}} \\\\

m\angle 1 = (5x + 14) \degree\\

m\angle 1 = (5\times 9+ 14) \degree\\

m\angle 1 = (45+ 14) \degree\\

\huge \purple{ \boxed{m\angle 1 =59\degree}}[/tex]

Answer:

c.  (-4, 4)

Step-by-step explanation:

y = 0.8x + 7.2

20x + 32y = 48

20x + 32y = 48

20x + 32(0.8x + 7.2) = 48

20x + 25.6x + 230.4 = 48

45.6x + 230.4 = 48

45.6x = -182.4

x = -4

y = 0.8x + 7.2

y = 0.8(-4) + 7.2

y = -3.2 + 7.2

y = 4

Answer:

y = 150x + 200

Step-by-step explanation:

Given the table :

Week (x) __ 0 ____ 1 ____ 2 ____3 _____ 4

Balance(y) :$200_ $350_ $500_ $650_ $800

Equation in slope - intercept form:

y = mx + c

Where

x and y are the independent(x) and dependent variables (y)

C = intercept, value of y, when x = 0

m = gradient change in y per change in x

Hence,

c = $200 ; y value when x = 0

m = change in x / change in y

m = (500 - 350) / ( 2 - 1)

m = $150

Hence, equation becomes :

y = 150x + 200

Answer:

84.3

Step-by-step explanation:

843 ÷ 10

The place value of 843 is

8 = Hundreds

4 = Tens

3 = Units or ones

Hence,

843 ÷ 10

= 843/10

= 84.3

Answer:

C. 1/8

Step-by-step explanation:

Dimensions of the Original Box:

Length = 40 inches

Width = 20 inches

Height = 8 inches

Volume of original box = L*W*H = 40*20*8 = 6,400 in³

Dimensions of the New Box (½ of the dimensions of the original box):

Length = ½*40 = 20 in

Width = ½*20 = 10 in

Height = ½*8 = 4 in

Volume of original box = L*W*H = 20*10*4 = 800 in³

Constant of proportionality between the volume of the new box and the volume of the original box = [tex] \frac{800}{6,400} = \frac{1}{8} [/tex]

Answer:

X = -16.75

Step-by-step explanation:

Distribute.

(x + 12)23 = 23x + 276

12 + 5x -1 = 11 + 5x

Combine like terms.

23x - 2x - 5x = 16x

11 - (276 + 3+16 ) = -284

16x = -284

x = -17.75

isolate the variable by dividing each side by factors that dont contain the variable inequality form:

M > 2

Answer:

y = 11t + 8

Step-by-step explanation:

Since the starting fee is 8 dollars and the additional costs are 11 dollars per ticket, you can write the equation as:

y = 11t + 8

Where "t" represents the amount of tickets bought.

2) 9.6x10⁹÷2x10³= 4800000

4) 6.9x10⁸= 2300

5) 5.6x10 -⁷ + 3.65x10 -⁶= 4.21x10 -⁶

6) 6.72x10⁵ - 3.65x10³= 668350

Answer:

Step-by-step explanation:

Given the function  f(x)=-x+1,x<0 and f(x) = x^2-1,x>0

when x = 4

f(4) =  -4+1

f(4) =  -3

Also f(4) = 4^2 -1

f(4) = 8-1

f(4) = 7

when x = -1

f(-1) =  -(-1)+1

f(-1) =  2

Also f(-1) = (-1)^2 -1

f(-1) = 1-1

f(-1) = 0

when x = -2

f(-2) =  -(-2)+1

f(-2) =  3

Also f(-2) = (-2)^2 -1

f(-2) = 4-1

f(-2) = 3

when x = 1

f(1) =  -1)+1

f(1) =  -2

Also f(1) = (1)^2 -1

f(1) = 1-1

f(1) = 0

From the calculation above, the correct statements are

A. F(4)=7

B f(-1)=2  

d. F(1)=0
